What is the current model of molecular architecture of membranes?

The current model of plasma membrane structure is fluid-mosaic model. According to fluid-mosaic model, there is a lipid bilayer that gives fluidity to the membrane and in which the protein molecules are embedded.  The membrane is mosaic because there is a pattern of different types of molecules that are put together. Molecules are constantly moving in two dimensions.

Components of the cell membrane include:

•Phospholipids – Form a bilayer  

•Cholesterol –improves stability and reduce fluidity

•Proteins –integral (transmembrane) or peripheral  

•Sugars-usually attached to proteins.

hello there,

igneous rock formed from below the surface would have more crystals because

answer: because magma cools more slowly than lava
